The attached file reports
foo.c: In function `main':
foo.c:19: warning: `result1' might be used uninitialized in this function
when compiled with avr-gcc -Os -Wall -c foo.c
gcc was built with
./configure --host=i686-pc-linux-gnu --enable-languages=c --target=avr --disable-nls
The same problem shows up in gcc-ss-3_3-20031110
foo.c:
char a;
static inline char rcombine(char r1, char r2)
{
return r1 ? 0 : r2;
}
static inline char Mod1_xx(void)
{
int i;
for (i = 0; i < 6; i++) a += i;
return 1;
}
static inline char Mod1_StdControl_init(void)
{
char result1;
char result2;
result1 = rcombine(2, 1);
result2 = Mod1_xx();
result1 = rcombine(result1, result2);
return result1;
}
int main(void)
{
Mod1_StdControl_init();
return 0;
}
